Abstract
A liquid cooled motor in which cooling pipelines are located in a casing around an outer periphery of a stator core, comprising deformed O-rings (5) provided around the circumferential edges of a deformed cross sectional hole (40) at ends of a casing (1), and circular cross sectional holes (41) of a housing (2, 3) which are connected to parts of the deformed cross sectional hole (40) to connect the casing (1) and the housing (2, 3). The invention is applied to a general small liquid cooled motor which needs high output and high revolution speed.
